The stamping is mainly will metallic and non-metallic sheet, with the aid of this press pressure, through the stamping mould pressing shaping, it basically has the following features: (1) the stamping is in material consumption, under the precondition of not by stamping out of manufacture its parts of light weight, good stiffness and sheet metal plastic deformation, through the internal structure of organization improved, make the stamping strength improved. (2) the stamping has higher precision and with module size uniformity, good interchangeability. Don't need further machining it satisfies the general assembly and use requirement. (3) stamping in stamping process, because material surface are not destroyed, it has good surface quality, appearance beautiful, it is smooth surface spray paint, electroplating, phosphate and other surface treatment provided convenience condition.
